Coding Bugs Leading to Security Vulnerabilities in Windows Drivers

Windows device drivers operate at the core of the operating system with high privileges, making any security flaws in their code potentially devastating. This article provides an academic overview of how common coding bugs in Windows drivers can lead to serious security vulnerabilities. We explain the architecture and role of Windows driversparticularly their kernel -level privilegesand examine typical programming errors such as buffer overflows, use of uninitialized memory, improper input validation, race conditions, and access control mistakes. Through two real -world case studies, we illustrate how these bugs have been exploited in practice. We then discuss tools and techniques for identifying driver vulnerabilities, including fuzz testing, symbolic execution, static analysis, andMicrosoft's specialized driver verification tools.Finally, we recommend secure development practices for driver developers to mitigate these issues.Annotated code snippets are provided to demonstrate insecure vs. secure coding practices, and an architectural diagram illustrates the potential impact of a malicious driver running with kernel -mode access.
